A person on IRC reported a build failure with the util-linux package, looking like this: for I in uname26 linux32 linux64 ; do \ cd /home/aep/consulting/chargery/tracker/output/target/usr/bin && ln -sf setarch $I ; \ done [...] /bin/sh: line 1: ./ln: cannot execute binary file: Exec format error /bin/sh: line 1: ./ln: cannot execute binary file: Exec format error /bin/sh: line 1: ./ln: cannot execute binary file: Exec format error The issue was an empty path in the PATH variable, which means "current working directory", causing a "ln" binary built by util-linux for the target to be used instead of the system-provided "ln". We already check a number of things in the PATH and LD_LIBRARY_PATH variables in support/dependencies/dependencies.sh, but we were not checking that PATH did not contain an empty path. This commit fixes that and takes this opportunity to simplify the test code for PATH and LD_LIBRARY_PATH. Signed-off-by: "Yann E.
